3 Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether they have approved the standards or not, from manufacturing, marketing, purchasing or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretation should be addressed to the sponsor whose name appears on the title page of this Standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this Standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute. This standard was developed by representative members of and approved by the Hollow Metal Manufacturers Association Division (HMMA) of the National Association of Architectural Metal Manufacturers (NAAMM) to provide their opinion and guidance on the specification and use of swinging sound control hollow metal doors and frames. This standard contains advisory information only and is published as a public service by NAAMM and its HMMA Division.

5 FOREWORD These specifications have been prepared in accordance with the CSI recommended Master Format 2012 with Part 1 - General, Part 2 - Product and Part 3 - Execution. Guide specifications are intended to be used as the basis for developing project specifications and must be edited to fit specific project requirements. Inapplicable provisions should be deleted, appropriate selections should be made where there are choices, and provisions applicable to the project should be added where necessary. Options are shown in brackets. Notes, recommendations and instructions to Specifiers are given in italics at the start of or directly following the sections to which they apply. Notes that contain permissive language are not considered part of the standard. Dates given with ASTM and other standards were current at the time this specification was published. When a more recent standard is available, the Specifier should verify its applicability to this Guide prior to its inclusion. While the CSI Section Format locates Delivery, Storage and Handling in Part 1, NAAMM standards include them under Part 3 Execution. This specification is comprehensive in regard to steel swinging sound control doors, door frames, sidelight, transom, borrowed light and fixed and operable window assemblies. It does not cover sliding sound control doors or other related components. Due to the complexity of the field of acoustics, it is advisable to retain an acoustical consultant or acoustician. Materials and fabrication methods are specified in detail in Part 2. Specific internal door constructions are not covered since they are proprietary to each manufacturer. Pillowing of the door can occur on some acoustical doors due to the acoustical material used on the interior of the door. Pillowing should not exceed 1/2 inch (12.7 mm), this will not affect the acoustical quality of the door. Doors and frames manufactured in accordance with these specifications have successfully met the testing and performance requirements of Section However, the materials and fabrication methods called for in these specifications, while providing an excellent guide, are not intended to restrict the use of other materials and methods where it can be demonstrated through the specific testing procedures in Section 1.05 that the construction can equal or exceed the performance levels specified. In order to ensure that a manufacturer s product meets the desired performance levels, the construction specifications must always include the Testing and Performance requirements of Section 1.05 and the Quality Assurance requirements of Section Note: the effectiveness of a door and frame unit is dependent on the sum of all parts of the unit functioning effectively in order to meet the STC rating, OITC rating and/or STL specified. This means that all portions of the unit, including the door, frame, hinging and latching hardware, perimeter gaskets and glazing, are tested as a unit. All components must be supplied as tested; glazing may be factory or field installed. The values stated in inch-pound units are to be regards as the standard. Corresponding metric values are included in parenthesis for reference purposes only. Hardware Considerations The selection of the hardware is a very important part of a successful sound control assembly. Sound doors are generally heavier than conventional hollow metal doors, particularly in applications with higher ratings. Their weight can vary, from 4.5 to 22 lbs. per square foot (22 to 98 kg/m2), depending on the STC rating, OITC and/or STL and thickness of the door; therefore, it is important to specify proper heavy-duty hardware capable of handling the door weight over the life of the installation. A minimum of three traditional butt hinges or two cam-lift hinges is required for all units. The door frame may be manufactured from thicker materials than those of conventional hollow metal frames for doors weighing only 4.5 to 6 lbs. per square foot (22 to 30 kg/m2). Sound control doors are built with specially designed proprietary cores. Any interference with this sound septum may cause a reduction in performance. Concealed vertical rod exit devices or concealed closers are examples of hardware that may interfere with the performance of the assembly. Another important part of the assembly is the gasketing around the door. Hardware that may interfere with this seal should be avoided. ii

6 Other Key Considerations Although many acoustic door frame assemblies closely resemble traditional hollow metal products, a number of additional factors must be taken into account. o Installation instructions provided by the manufacturer must be followed in order to obtain the desired acoustical rating. o The quality of the installation of the door, frame, gasketing and hardware is essential. o The flatness of the floor beneath the door is critical. o The manufacturer of sound control assemblies can provide advice on installation and hardware selection. As is the case with any product that is certified based on performance done under controlled laboratory (STC) conditions, sound control door assemblies installed under less well-controlled job site (FSTC) conditions can be expected to have a 4 to 5 point reduction in STC performance. Depending upon door and frame constructions, along with hardware and gasketing systems, sound control hollow metal door and window assemblies are available from NAAMM-HMMA members to suit a wide range of performance criteria. Specifiers are encouraged to consult member manufacturers for assistance with technical product information for your application. For hollow metal doors and frames not requiring sound control hollow metal door assemblies give consideration to NAAMM HMMA 860, Guide Specifications for Hollow Metal Doors and Frames or ANSI/NAAMM HMMA 867, Guide Specifications for Commercial Laminated Core Hollow Metal Doors and Frames. For commercial steel doors and frames expected to be subjected to a more rigorous level of use, ANSI/NAAMM HMMA 861, Guide Specifications for Commercial Hollow Metal Doors and Frames, may be used. For situations where corrosion resistance beyond that of typical commercial steel door and frame applications, or where specialized aesthetic appearance are significant design criteria, consideration should be given to ANSI/NAAMM HMMA 866, Guide Specifications for Stainless Steel Hollow Metal Doors and Frames. If security is a factor, there are two hollow metal standards available - ANSI/NAAMM HMMA 862, Guide Specifications for Commercial Security Hollow Doors and Frames and ANSI/NAAMM HMMA 863, Guide Specifications for Detention Security Hollow Metal Doors and Frames. iii

9 AF. NAAMM HMMA 850, Fire-Rated Hollow Metal Doors and Frames The following standards are used only for neutral pressure fire test methods and should be deleted from project specifications when positive pressure is required by the governing building code: ANSI/UL10B (H), CAN/ULC-S104 (T) and CAN4-S106 (U). Conversely, ANSI/UL 10C (I) is used only for positive pressure fire tests and should be deleted from project specifications requiring neutral pressure fire tests. ANSI/NFPA 252 (E), ANSI/NFPA 257 (F) and ANSI/UL 9 (G) reference both neutral pressure and positive pressure fire test methods and as such should be included in all project specifications, except those requiring compliance with Canadian Building Codes. Only project specifications requiring compliance with Canadian Building Codes should include CAN/ULC-S104(T) and CAN4-S106 (U). Refer to Appendix 3 for a list of the Standards Writing or Accreditation Organizations referenced in Section TESTING AND PERFORMANCE A. Conduct sound control performance testing on a fully operable assembly in accordance with ASTM E 90, ASTM E 413 and ASTM E 1332, by an independent testing laboratory. Qualify the laboratory referenced in the test report and/or certification under the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute for Science and Technology (NIST) or the International Accreditation Service (IAS) under the International Laboratory Accreditation Cooperation (ILAC) agreement. See Appendix 4 for an over-view of ASTM E 90, E 413, and ASTM E B. Labeled Fire-Rated and/or Smoke Control Door and Frame Product 1. Where determined and scheduled by the Architect; a. Provide Listed or Classified doors, panels, frames, transom frames, sidelight, borrowed light and window assemblies bearing the label of a testing agency having a factory inspection service for openings requiring fire protection and/or smoke control ratings. b. Test doors, panels, frames, transom frames and sidelight assemblies in accordance with [ANSI/NFPA 252 or ANSI/UL 10B or CAN/ULC-S104] [ANSI/NFPA 252 or ANSI/UL 10C] [and/or] [ANSI/UL 1784]. c. Test borrowed light and window assemblies in accordance with [ANSI/UL9 or ANSI/NFPA 257] [CAN4-S106]. d. Construct products as Listed or Classified for labeling. ANSI/UL10C provides for positive pressure testing to accommodate the requirements of some jurisdictions and should be included only for such. ANSI/UL10B, CAN/ULC-S104 and CAN4-S106 provide for neutral pressure testing to accommodate the requirements of the remaining jurisdictions and should be included only for such. ANSI/NFPA 252, ANSI/NFPA 257 and ANSI/UL 9 cover both neutral and positive pressure testing and therefore should be included in all project specifications, except when compliance with Canadian Building Codes is required. ANSI/UL 1784 provides for smoke control assembly testing required by ANSI/NPFA 105 to accommodate these specific requirements and should be included only when required. Include CAN/ULC-S104 and CAN4-S106 only for projects requiring conformance with Canadian Building Codes. 2. For any door or frame product specified by the Architect to be fire-rated, which cannot qualify for labeling due to design, hardware or other reason, advise the Architect, in the submittal 3

10 documents. Advise the Architect when hardware, glazing or other options specified, unknown at the time of submittal document preparation, affect fire labeling eligibility. The Specifier must ensure that all performance based criteria such as fire-protection rating, temperature-rise rating, smoke control, STC, OITC and/or STL for each opening are clearly detailed by the Architect on the project door schedules. STC and OITC ratings are specified as numeric values whereas STL should be specified as decibels within a critical frequency range for the offending sound (ie: 40 db minimum at 500 to 1250 Hz). C.

11 E. Do not proceed with fabrication without receipt of approved submittal drawings and approved hardware schedules. PART 2 - PRODUCTS The approved submittal drawings and the approved hardware schedule are the versions that have been provided to the hollow metal sound control door manufacturer at the time of release for fabrication. These drawings and the schedule are considered part of the project construction documents. Insist upon receiving detailed templates along with approved submittal drawings to assure proper coordination between Contractor and installers DOORS A. Materials 1. Steel a. Cold-rolled steel conforming to ASTM A 1008/A 1008M, CS, Type B b. Hot-rolled, pickled and oiled (HRPO) steel conforming to ASTM A 1011/A 1011M, CS, Type B c. Zinc-coated steel conforming to ASTM A 653/A 653M, CS, Type B 2. Door Cores B. Construction a. Manufacturer's standard internal construction of doors as required to meet the [STC rating], [OITC rating] and/or [STL] specified. ANSI and ASTM Standards no longer utilize gage to define steel thickness. In this Specification steel is expressed in terms of minimum decimal inch (millimeter) thickness. Dimensions or sizes traditionally expressed in fractional inches are shown in decimal inches (millimeters). HMMA has developed a series of Tables, (NAAMM HMMA 803) included as Appendix 1 of this Specification, to summarize the imperial standards and their corresponding metric values. 1. Fabricate door types, sizes and constructions in accordance with the contract documents and meeting the performance requirements of Section Door face sheet thickness as required to meet STC, OITC and/or STL specified but not less than in. (1.06 mm). a. Interior doors constructed of in. (1.06 mm) minimum thickness commercial quality steel sheet, free of scale, pitting or surface defects, conforming to ASTM A 1008/A 1008M for cold-rolled steel, ASTM A 653/A 653M CS Type B Coating Designation A25 (ZF75) for zinc-coated steel, or ASTM A 1011/A 1011M CS Type B for hot-rolled pickled and oiled steel. For interior areas subject to corrosive conditions it is recommended that zinc-coated face sheets, as specified in 2.01.B.2.b, be used. b. Exterior door face sheets in. (1.06 mm) minimum thickness zinc coated steel conforming to ASTM A 653/A 653M CS Type B Coating Designation G60 (Z180) or A60 (ZF180), free of scale, pitting or surface defects. 3. Door thickness as required to meet STC rating, OITC rating and/or STL specified. 4. Fabricate doors neat in appearance, with edge bends true, straight and of minimum radius for the thickness of metal used. 5. Prior to shipment mark each door with an identification number as shown on the approved submittal drawings. 6. Door construction as required by the door manufacturer to maintain contact with acoustical gaskets. 5

12 7. Provide top and bottom edges of doors as required by the door manufacturer to maintain contact with acoustical gaskets or to accommodate acoustical seals such as automatic door bottoms. a. Close top and bottom of door with a continuous steel channel, not less than in. (1.34 mm) thickness, welded or laminated to both face sheets. 8. Exterior doors and where otherwise scheduled by the Architect, close doors flush at the top edge with a steel closure channel. Where required for attachment of weather-stripping, provide a flush steel closure channel at the bottom edge with openings to permit the escape of entrapped moisture. Sound attenuation performance is partly dependent upon the type of hardware and sound seals used. Coordination of this Section and the Door Hardware Section is required to avoid duplication of products and assure proper performance. Sound control doors are built with specially designed proprietary cores. Any interference with this sound septum may cause a reduction in performance. Concealed vertical rod exit devices or concealed closers are examples of hardware that may interfere with the performance of the assembly. Sound control assemblies include the gasketing around the perimeter of the door. Hardware that interferes with this seal must be avoided. An experienced sound control door manufacturer can provide advice on the best hardware to use. 9. Hardware Reinforcements and Preparations a. Hardware supplier to coordinate hardware compatibility with the sound door assembly manufacturer. b. Advise the Architect in the submittal documents of any hardware preparations that compromise the sound control capabilities of the assembly prior to fabrication. c.

Where electronic hardware is indicated on the approved hardware schedule, provide wire access from hinge edge to device in accordance with the templates provided. 10. Glazing Assemblies (if applicable) Glass is relatively permeable to sound; therefore, the manufacturer s test results regarding allowable glazing material and sizes must be followed to retain sound retarding characteristics of the assembly. 6

13 a. Where specified or scheduled, provide steel fixed glass molding and removable stop glazing assemblies, matching the material type of the door face sheets, as tested by the manufacturer for the model and sound rating specified, to secure glazing materials furnished by and installed [at the factory] [in the field by a qualified glazer under Section ]. b. Advise the Architect in the submittal documents if glazing specified or scheduled by the Architect compromises the sound control capabilities of the door prior to fabrication. c. When dual glazed systems are provided, each piece of glazing must be capable of being removed independently.

17 2.04 MANUFACTURING TOLERANCES The manufacturer of the doors and frames is responsible only for the manufacturing tolerances listed in Section 2.04.A. The final clearances and relationship between door and frame depend on the setting of the frame and the hanging and adjustment of the door and hardware (see Section 3.02). A. Maintain manufacturing tolerances within the following limits: 1. Frame Product for Single door or Pair of Doors a. Width, measured between rabbets at the head: nominal opening width + 1/16 in. (1.58 mm), - 1/32 in. (0.79 mm) b. Height (total length of jamb rabbet): nominal opening height +1/16 in. (1.58 mm), - 1/32 in. (0.79 mm) 2. Doors 2.05 HARDWARE c.

18 4. Exit hardware in. (965 mm) to centerline of cross bar or as shown on hardware template 5. Roller Latches in. (1143 mm) to centerline of latch B. Sill Condition: 2.06 FINISH The hardware locations listed in this specification reflects HMMA s 830, "Hardware Selection for Hollow Metal Doors and Frames" and 831, Recommended Hardware Locations for Hollow Metal Doors and Frames. However, specific hardware and/or individual door frame manufacturers designs may require different locations. 1. The floor area under a sound control door must be flat, level, and smooth. 2. Where required for assembly compliance, furnish a smooth, flush [stainless steel] [aluminum] [hard surface] threshold for the door bottom to seal against when the door is in the closed position. The sound door assembly manufacturer is not responsible for thresholds or floor conditions which prevent door bottom gasketing systems from providing the required acoustical seal. Consult the sound door manufacturer for guidance. A. After fabrication, fill and sand all tool marks and surface imperfections as required to make face sheets, vertical edges and weld joints free from irregularities and dressed smooth. B. After appropriate metal preparation, exposed surfaces of door and frame product manufactured from cold-rolled, hot-rolled, A25 (ZF75), or G60 (Z180) zinc-coated steel shall receive a factory applied rust inhibitive primer which meets or exceeds the performance requirements of Section 1.05.C. C. All exposed surfaces of door and frame product manufactured from A40 (ZF120) or heavier zinccoated galvanneal steel shall have areas where zinc coating has been removed during fabrication touched-up with a zinc-rich rust inhibitive primer or shall receive a factory applied fullcoat rust inhibitive primer. D. All primer must be fully cured prior to shipment. All primer and finish paint must be formulated for Direct to Metal (DTM) application. Some types of paint will not dry completely. It is imperative that the type of paint selected dries completely and results in a smooth, hard surface. If the wrong type of finish paint is used, the paint will become soft and sticky. This condition, called plasticizer migration, occurs when solvents from uncured paint reacts with neoprene or vinyl gaskets, particularly with some latex paints. The problem appears to be the paints slow release of solvent that dissolves out the plasticizer in the acoustical gaskets. To avoid this problem we recommend using a low VOC or no VOC finish paint. VOC stands for volatile organic compound. PART 3 - EXECUTION 3.01 SITE STORAGE AND PROTECTION OF ACOUSTICAL MATERIALS Correct site storage and protection is essential to the proper performance of doors and frame product. The requirements for proper storage are given in the following sections. However, it is important to recognize that proper storage is not the responsibility of the sound control hollow metal manufacturer. For this reason the requirements for installation of hollow metal sound control doors and frames is in the section of the specifications where installation of work is specified, Section For additional information regarding storage see NAAMM HMMA 840, Guide Specification for Installation and Storage of Hollow Metal Doors and Frames. 12

19 A. The contractor responsible for receiving sound control hollow metal product must remove all wraps or covers upon delivery at the building site and ensure that any scratches or disfigurement caused by shipping or handling are promptly cleaned and touched up with a rust inhibitive Directto-Metal (DTM) primer. B. The contractor responsible for receiving sound control hollow metal product shall ensure that materials are properly stored on planks or dunnage in a dry location. Doors and frame product must be stored in a vertical position, spaced by blocking. Store doors on their top edge, eliminating the potential of damage to the bottom seal. Cover all materials to protect them from damage but in such a manner as to permit air circulation. Figure 2 of this guide illustrates recommended storage positioning. Refer to NAAMM-HMMA 840 for additional information INSTALLATION Correct installation is essential to the proper performance of doors and frame product. The requirements for proper installation are given in the following Sections. However it is important to recognize that installation is not the responsibility of the hollow metal manufacturer. For this reason the requirements for installation should be included in Sections , , and/or of the project specifications, as appropriate. For additional information see NAAMM HMMA 840, Guide Specifications for Installation and Storage of Hollow Metal Doors and Frames. A. The Installer is responsible for the following: 1. Prior to installation, check the area of floor on which the frame product is to be installed and within the path of the door swing, for flatness and correct as necessary. 2. Prior to installation, remove temporary spreaders. Check each door and frame product for correct size, swing, fire rating and opening number. 3. Prior to installation, isolate and protect from grout and antifreeze agents, all interior surfaces of perimeter frame product sections to be installed in masonry or concrete walls. The drawbacks and benefits associated with the use of water based masonry grouts, with or without antifreeze agents, should be carefully weighed during the detailing and specification process. Grouting of mullions and other closed sections is not recommended and plaster based grouts should not be used. Refer to NAAMM HMMA Tech Note, HMMA 820 TN01-03, Grouting Hollow Metal Frames, included as Appendix 2, for further guidance. 4. During the setting of frame product check and correct as necessary for opening width, opening height, squareness, alignment, twist and plumbness. Maintain installation tolerances within the following limits: a. Opening Width... measured from rabbet to rabbet at top, middle and bottom of frame; + 1/16 in. (1.58 mm), - 1/32 in. (0.79 mm) b. Opening Height... measured vertically between the frame head rabbet and top of floor or bottom of frame minus jamb extensions at each jamb and across the head; + 1/16 in. (1.58 mm), - 1/32 in. (0.79 mm) c. Squareness... measured on a line from jamb, perpendicular to frame head; not to exceed 1/16 in. (1.58 mm) d. Alignment... measured at jambs on a horizontal line parallel to the plane of the face; not to exceed 1/16 in. (1.58 mm) e. Twist... measured at opposite face corners of jambs on parallel lines perpendicular to the plane of the door rabbet; not to exceed 1/16 in. (1.58 mm) f. Plumbness... measured at the jambs on a perpendicular line from the head to the floor; not to exceed 1/16 in. (1.58 mm) 13

20 The above tolerances provide a reasonable guideline for proper installation of steel frame product. However, it should be noted that the cumulative effect of the installation tolerances at or near their maximum levels could result in sufficient misalignment to prevent the door from functioning properly. Installers should be careful not to create a tolerance buildup. Tolerance buildup occurs when several tolerances are at or near their maximums. The details in Figure 3 illustrate methods of measuring the above specified tolerances. 5. Grout guards are intended to protect hardware mortises and tapped holes from masonry grout of 4 in. (101 mm) maximum slump consistency which is hand troweled in place. If a lighter consistency grout (greater than 4 in. (101 mm) slump when tested in accordance with ASTM C 143/C 143M) is to be used, special precautions must be taken in the field by the installer to protect the aforementioned. 6. Frame products are not intended or designed to act as forms for grout or concrete. Grout frame sections in lifts or take precautions to ensure that frames are not deformed or damaged by the hydraulic forces that occur during this process. 7. Keep steel surfaces free of grout, tar and/or other bonding materials or sealers. Promptly clean grout, tar, bonding materials or sealers off doors and frame product. 8. Installer to refinish to match original, any marks caused by spreader removal. 9. Exposed hollow metal surfaces which have been scratched or otherwise marred during installation, cleaning, and/or field welding, shall promptly be finished smooth, cleaned, treated for maximum paint adhesion and touched up with a rust inhibitive primer comparable to and compatible with the shop applied primer and finish paint specified in Section All touch-up primer and finish paint must be formulated for Direct to Metal (DTM) application. 10. Install acoustic doors and frame product in accordance with the manufacturer's installation instructions, test reports and/or certifications. 11. Install labeled fire doors and frame product in accordance with the terms of their listings, ANSI/NFPA 80 or the local Authority Having Jurisdiction. 12. Install hardware in accordance with hardware manufacturer s templates and instructions. 13. Maintain proper door clearances in accordance with Section 2.01.B.11, except for special conditions otherwise noted. Where necessary, metal hinge shims, furnished by installer, are permitted to maintain clearances. 14. Install and adjust acoustical seals in accordance with the sound door manufacturer's installation instructions. 15. Install glazing materials in accordance with Section Finish paint in accordance with the sound door assembly and paint manufacturer's instructions and Section Sound door and frame product to be finished with a DTM (Direct-to-Metal) paint with a gloss rating not greater than 20% reflectance, measured using a 60 degree gloss meter. Do not paint gasketing materials FIELD VERIFICATION (Optional) A. Engage a qualified representative approved by the manufacturer to: 1. Inspect completed installation of a representative sample of door and frame assemblies. 2. Test all components through a minimum of ten complete cycles of operation. 3. Verify each component is correctly installed. 4. Direct installer in adjusting components for correct operation. 5. Issue certified statement of compliance of installed door and frame assemblies to Architect as per approved contract documents. 14
